WebBFS and DFS work on both directed and undirected graphs, as shown in the figures above. If the underlying graph is disconnected, BFS and DFS can only traverse the connected component that the given starting node belongs to. BFS cannot be used to find shortest paths on weighted graphs. See Dijkstra’s algorithm for that! WebIf the edges are all length x=1 (or the same length), then BFS will find all paths of length 1x from the source, followed by all paths of length 2x, followed by all paths of length 3x, … WebBFS and shortest path help needed. So basically; I have this working. I have an adjacency list that represents a 3 x 3 grid and a shortestPath () function that takes two arguments, start and end. When invoked it returns all the correct data. However; I need to refactor it so that the grid uses coordinates instead of values. diary layout
